Answer: y = 4x + 6
Step-by-step explanation:
Isolate y on the left by adding 4x to both sides of the equation.
In slope intercept form , now you have the slope, m = 4
And the y-intercept, b = 6

Find the slope of a line passing through: (3,5), (4,12)
Answer:
7
Step-by-step explanation:
Answer:
The slope is m=7
Step-by-step explanation:
The Slope of a Line
Suppose we have a line that passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (3,5) and (4,12), thus: x1=3, y1=5, x2=4, y2=12. Substituting:
[tex]\displaystyle m=\frac{12-5}{4-3}=\frac{7}{1}=7[/tex]
The slope is m=7
factorise x square - 3 x minus 2
Answer:
The answer is below
Step-by-step explanation:
The equation x² - 3x - 2 cannot be factorized, I think the correct question is:
factorize x² - 3x + 2
Solution:
A quadratic equation is a polynomial equation of the second degree (that is there is at least one term with a degree of 2).
The standard form of a quadratic equation is given by the equation:
ax² + bx + c = 0
Where a, b, and c being constants and x is the unknown variable.
Given:
x² - 3x + 2
= x² - 2x - x + 2
= x(x - 2) -1(x - 2)
= (x - 1)(x - 2)

4x - 12 = 8x + 24
O A. x=-9
O
B. X=-3
O C. x=1
О O
D. x= 3
Answer:
-9
Step-by-step explanation:
4x-12=8x+24
we change the signs when we bring 8x on the left hand side so positive 8x becomes -8x.
4x-8x-12=24
we change sign when we bring -12 on the right hand side it becomes +12
4x-8x=24+12
-4x=36
x=36/-4
x=-4

Given:
On a number line, point A is at -6 and point B is at 7.
To find:
The distance between point A and point B.
Solution:
In the given number line,
Point A = -6
Point B = 7
We need to find the difference between point A and point B to find the distance between them.
Since 7 > -6. therefore,
[tex]\text{Distance}=B-A[/tex]
[tex]\text{Distance}=7-(-6)[/tex]
[tex]\text{Distance}=7+6[/tex]
[tex]\text{Distance}=13[/tex]
Hence, the distance between point A and point B is 13 units.

The line x=40 is horizontal line true or false??
Answer:
True.
x=40 is on the x-axis meaning that it is a horizontal line.
Answer:
x = 40 is actually a vertical line.
Step-by-step explanation:
Let (x, y) where x = 40. We will get (40,y).
Because there is no y-term or y-value. We can say that y is the set of all real numbers. That makes the graph a vertical.
A horizontal line would be y = b where b is a constant. We call y = b the Constant Function where the graph is a horizontal line.

Answer:
A. 8.6 km
B. 34.4 km
Step-by-step explanation:
All the sides of a square have the same value. So because one side is 8.6 km, we know that all the other sides are also 8.6 km.
We get the perimeter by adding up all the sides of a polygon together. Since all the sides are 8.6 km, we can multiply 8.6 by 4. The perimeter is 34.4 km.

A salesperson earns a weekly salary of $150 plus a 15% commission of her total sales. Her total sales for the week is $15,000. How much does she earn for the week?
$172.50
$172.50
$2,250.00
$2,250.00
$2,400.00
$2,400.00
$15,150.00
As total salary of salesperson is sum of the fixed salary and commission. The salesperson earned $2400 for the week.
Given-
Fixed salary of the salesperson is $150 per week.
Total commission of the salesperson is 15 percent of his sales.
Total sales by the salesperson is $15000.
We have to find out the total earning of the salesperson of the week. As total salary of salesperson is sum of the fixed salary [tex]x[/tex] and commission [tex]y[/tex]. We know that her weekly salary is $150. Therefore find out first her commission for the sales for that week.
The commission [tex]y[/tex] earned by the salesperson for the week is fifteen percent of the total sales.Hence the fifteen percent of the total sales is,
[tex]y=15000\times\dfrac{15}{100}[/tex]
[tex]y=150\times15[/tex]
[tex]y=2250[/tex]
Thus the commission earned by the salesperson is $2250.
Now add this commission earned by the salesperson [tex]y[/tex] and her fixed salary [tex]x[/tex] to calculate the Total salary earn by the salesperson s is,
[tex]s=x+y[/tex]
[tex]s=150+2250[/tex]
[tex]s=2400[/tex]
Hence, The salesperson earned $2400 for the week.

Write an exponential function to model earthquake intensity as a function of a Richter Scale number. How can
you use your function to compare the intensity of the 1811 New Madrid and the 1906 San Francisco
earthquakes?
Answer:
1. The exponential function to model earthquake intensity as a function of a Richer Scale number is f(x)=10^x (to the power of x)
2. To compare the intensity of the 1811 New Madrid earthquake and the 1906 San Francisco earthquake, the function can be used to find the ratio of f(x) for x=8.1 to f(x) for x=7.8
3. The 1811 New Madrid earthquake was about two times the intensity of the 1906 San Francisco earthquake.

the year, Wayne was typing 48 words per
minute. Was this an increase or decrease?
What is the percent change?
Increase word per minute and percentage changed are 18 word per minute and 60%
Given that;Beginning typing speed = 30 word per minute
Ending typing speed = 48 word per minute
Find:Increase word per minutePercentage changeComputation:Increase word per minute = Ending typing speed - Beginning typing speed
Increase word per minute = 48 - 30
Increase word per minute = 18 word per minutes
Percentage change = [18 / 30]100
Percentage change = [0.6]100
Percentage change = 60%

A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall. How tall is the lighthouse?
Answer:
I do believe that the lighthouse is 160 feet tall.
Step-by-step explanation:
I do believe this is the right answer. Hope this helps you!
The required height of the lighthouse is given as 160 ft tall.
Given that,
A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall.
The scale factor is defined as the ratio of the modified change in length to the original length.
What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
here,
scale factor = 1 / 8 in per ft
Now,
The actual length of the lighthouse = 20 / [1 / 8]
= 20 × 8 = 160 ft
Thus, the required height of the lighthouse is given as 160 ft tall.
